Personally I would like to see the hooks for op-codes stay in place, I think they offer a lot of possibilities for extensions. Andi, what do you mean "create the handler execution architecture"? I'm a little confused to what you are referring to.
I mean that what we have to day is the function handler dispatch architecture (i.e. what it is in PHP 5.0.x). In PHP 4, we had switch().
Again, I think the opcode hook could be solved for people who want to do so by having such a version floating around in the address space for extensions that want to use it. It's a bit more memory but it's memory that should be shared.
PS -- I hated the switch() method ;)
It was definitely uglier and that's why I made the change but in many cases the "goto and/or switch" dispatch methods are faster.
